The KI-211C is a low-cost way to add glideslope capability with King quality. It contains an internal 20 channel Glideslope Receiver, instead of the more common 40 channels.

The KI-211C will provide glideslope guidance on the following frequencies:

108 to 111

.1 , .3 , .5 , .7 , and .9 (i.e. the odd decimals)

On approaches that use one of the other 20 channels, the pilot will get Localizer guidance, but not Glideslope, turning it into a non-precision approach. At many airports with multiple approaches, at least one of them will provide Glideslope with the KI-211C.

We recommend the KI-211C to replace an existing KI-211C. If you are considering this item for a new installation, we recommend you consider the KI-214 instead. The KI-214 is a bit more expensive, but you will know that every ILS is available to you.
